Case ReportsExtra-anatomic lateral bypass combined with embolization of the femoral stump for management of groin infection and bleeding due to metastatic carcinoma of the penis.
We report a possible treatment strategy for a patient with squamous cell carcinoma of the penis in hemorrhagic shock, due to erosion of the right femoral artery by metastatic inguinal lymph nodes. Because of coexistent groin infection and the inability to perform radical excision, the patient was treated with a lateral extra-anatomic iliac femoral prosthetic bypass; to prevent further bleeding, the femoral stump was embolized percutaneously. The patient was discharged home and did not experience any vascular complications during the follow-up, until death due to pulmonary metastasis.

ReviewDoes positron emission tomography offer prognostic information in malignant pleural mesothelioma?
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether positron emission tomography is useful in the diagnosis and prognosis of malignant pleural mesothelioma (MPM). Altogether 136 papers were found using the reported search, of which 15 represented the best evidence to answer the clinical question. ⋯ Overall, PET accurately diagnoses MPM, predicts survival and disease recurrence. It can guide further management by predicting the response to chemotherapy and excluding surgery in patients with extrathoracic disease. Combined PET-CT has additional benefits in accurately staging disease.

Multicenter StudyProcedural, 30-day and one year outcome following CoreValve or Edwards transcatheter aortic valve implantation: results of the Belgian national registry.
We report clinical outcomes following transcatheter aortic valve implantation (TAVI), using the CoreValve revalving system (18 Fr transfemoral or subclavian) or the Edwards Sapien valve (22 Fr transfemoral or 24 Fr transapical) as part of a Belgian prospective non-randomized multicentre registry. All 15 Belgian centres performing TAVI participated to this registry (seven exclusively Edwards Sapien, eight exclusively CoreValve). All consecutive high-risk symptomatic patients with severe aortic stenosis were evaluated by a heart team and screened for eligibility for TAVI. ⋯ One-month mortality was both related to cardiac and non-cardiac reasons. Overall one-year survival was 78% in the CoreValve transfemoral treated patients, 100% in the CoreValve subclavian treated patients, 82% in the Edwards transfemoral treated patients and 63% in the Edwards transapical treated patients. This mid-term mortality was mainly related to age-related, non-cardiac complications.

Comparative StudyExtracorporeal membrane oxygenation for acute respiratory distress syndrome: is the configuration mode an important predictor for the outcome?
Extracorporeal membrane oxygenation (ECMO) is increasingly applied as rescue-therapy for patients with severe acute respiratory distress syndrome (ARDS). Here, we evaluate the effect of different configuration strategies (venovenous vs. venoarterial vs. veno-venoarterial) on the outcome. From 2006 to 2008, 30 patients received ECMO for severe ARDS. ⋯ Although univariate analysis could not rule out a significant predictor for the outcome, there was a trend visible to decreased mortality in the vva-group when compared to vv- and va-groups (27% vs. 63% vs. 75%; P = 0.057). ECMO provides a survival benefit in patients when considering a predicted mortality rate of 80% in ARDS. The configuration mode appears to impact the outcome as the veno-venoarterial appears to further improve the survival in this subset of patients.

Comparative StudyFour-side near-infrared spectroscopy measured in a paediatric population during surgery for congenital heart disease.
In this study we monitored renal, hepatic and muscular oxygen saturations by near-infrared spectroscopy and we evaluated the correlation with variables that could affect tissue oxygenation in 16 paediatric patients during surgical heart procedure. We considered the following phases: 1) basal time (after induction of anaesthesia and before median sternotomy), 2) before starting cardiopulmonary bypass, 3) 15 min after starting it, 4) at half time, 5) 15 min before the end, 6) at the end, 7) 15 min after the end, and 8) 10 min before paediatric intensive care unit admission. Heart rate, mean arterial pressure, peripheral oxygen saturation, serum lactate, haemoglobin, blood gas analysis, and rectal temperature were registered. ⋯ A statistically significative inverse correlation between cerebral rSO(2) and pH was observed. In conclusion, during paediatric heart surgery a vulnerable period was identified. We underline the necessity to monitor this phase.
